Dear all,
I am probably doing something silly and don't realise it but here goes...
I am trying to find the eigen values and eigen vectors of a matrix, but
maxima keeps giving me an error (run on win XP in wxMaxima)
(%i37)E:
matrix([1,-1,0,0,0,0,0],[-1,3,-1,0,-1,0,0],[0,-1,3,-1,0,-1,0],[0,0,-1,3,0,0,-1],[0,
-1,0,0,3,-1,0],[0,0,-1,0,-1,4,-1],[0,0,0,-1,0,-1,4]);
(%o37)
matrix([1,-1,0,0,0,0,0],[-1,3,-1,0,-1,0,0],[0,-1,3,-1,0,-1,0],[0,0,-1,3,0,0,-1],[0,-1,0,0,3,-1,0],[0,0,-1,0,-1,4,-1],[0,0,0,-1,0,-1,4])
(%i38) eigenvalues(E);
solve is unable to find the roots of the characteristic polynomial.
(%o38) []
and for eigenvectors ...
(%i42)eigenvectors(E);
solve is unable to find the roots of the characteristic polynomial.
(%o42) []
I have tried the same problem in R and I get an answer (in the blink of an
eye). Can anyone let me know what the problem is?
Kind Regards
